Nelson and Ramos sped on toward Mars in their tiny plastic-bubble spacecraft. They were on the alert - it didn't pay to take anything for granted in the Big Vacuum...The way between the worlds was mostly empty space - except for the outlaws of the void who drifted, patiently and vengefully waiting for a victim, then struck!

Air puffed out... and Nelson and Ramos were fighting for their lives... A Million Miles Beyond the Moon!
